WARREN B. CANNON, OF KALAMAZOO, MICHIGAN, ASSIGNOR TO THE IVILLIAMS MANUFACTURING slLo.

SPECIFICATION forming part of Letters Patent No. 624,751, dated May 9, 1,899.

Application filed October 17, 1898.

To @ZZ whom, it may concern.-

Beit known that I, WARREN B. CANNON, a citizen of theUnited States, residing in Kalamazoo, county of Kalamazoo, State of Michigan, have invented a new and useful Silo, of which the following is a specification.

The object of this invention is to provide a silo having a series of door-openings one above another for putting food into the silo from the cutting-machine and removing the same.

Afurtherobject consists in the peculiar and convenient means of fastening the doors in the door-openin gs, as particularly set forth below.

In the drawings forming a part of this speciiication, Figure l is a front elevation of the silo looking at it against the door side; Fig. 2, a section on lines a d and c c in Fig. l looking from a point above and enlarged; Fig. 3, an enlarged view of the door in Fig. l in perspective, and Fig. Il is an enlarged section on line e e in Fig. l looking from a point at the` left.

Referring to the parts of the drawings pointed out by numerals, 5 are the staves of which the silo is composed in a round form like a tub or barrel. These silos are made Very high, so that it becomes necessary to have a series of door-openings 6 one above another, as in Fig. l, through which to put the food and remove the same, such as cut-up cornstalks or other vegetation, and when the silo is full up to one door-opening a door 7 isv iitted into the door-opening, as at bottom ofv Fig. 1 and in Fig. 2, and then the filling goes on until another door-opening is reached, and so on. In emptying the silo the process is reversed. In filling, the ordinarypractiee is to cutthe feed and deliver it to the several door-openings by a machine with adjustable elevator for the purpose. With this explanation of the use I will now proceed to describe the balance of the construction.

The door-frame consists of two strips 9 and l0, separated a distance apart laterally, as is required for the door-openings 6, by short staves ll, which alternate verticallywith the door-openings. The staves and door-frame are bound together by the hoops 12, as in Fig.

Serial No. 693.824.. (No model.)

l. Between the staves 5 and the side pieces I 'forming shoulders 16, against which the door detachably lits, as in Fig. 2, said door beingshown at 7. To the ends of the short staves, at the top and bottom ofthe door-openings, are attached strips of metal 19, which project a little beyond the end of thestaves and form shoulders or flanges 20, Fig. 4, for the top and bottom of the door to fit against, Figs. 2 and '3.

The doors are made from short staves 2l, held together by outwardly-protrudin g cleats 22, Figs. 2 and 3. These cleats are handy to take hold of in fitting the door in place. These doors are provided with a rubber packin g-strip 24, Figs. 3 and 4., on' their outer face around the edge, so that when the door is in place the rubber comes against the shoulders of the side pieces of the door-frame and against the flanges 19, Figs. 2 and 4. The doors are also provided with outwardly-projecting bolts y 25 and 26 at the four corners, and the doors are placed in position by putting them inside the silo with the convex side facing outward, pulling them against the rubber `packingstrips that come between said doors and the shoulders of the side pieces of the doorframes and against the flanges 19, Figs. 2 and 4., and then slipping the securing-trusses 27 onto the outwardly-projecting bolts 25 and 26, and by screwing nuts onto said bolts the doors are firmly drawn into place and securely held there. The end projections 28 of the securing-trusses 27 are preferably made of metal castings and are detachably rested againstthe side pieces of the door-frame, as in Figs. l and 2.

A silo thus made is practically air-tight, so as to preserve the food in good condition, and is comparatively cheap and conveniently operated.

Having thus described my invention, what' I claim as new, and desire to secure by Letters Patent of the United States, is

A round silo, constructed of staves, having a series of door-openings and shoulders and Aflanges for the doors to fit against, in oombiunto set my hand in the presenoe of two Witnation With the doors, the detachable trusses nesses.
